wwmw' Rebaued May 28, 1940 This invention relates in general to control sound distribution devices and more partrol unit which provides means for selecting and reproducing any recorded sound rendition availconnected.

Automatic selective phonographs have been commercially marketed for many years, and while these machines are highly efllcient insofar as the mechanism is concerned, they all have a common sound distributing point, namely. the loud speaker in the cabinet. I

Usually the automatic phonograph is used in 5 public places where patrons are seated at a distance from the machine or even in separate rooms or booths, and the patron must therefore leave his position and walk to the machine in order to play it; This annoyance ofttimes greatly limits the plays of the phonograph. Moreover, the patron has no control over the volume emitted by the phonograph, and inasmuch as personal tastes difler greatly in this regard, quite frequently the volume is adjusted either too loud or too soft to suit all listeners. Up to the time of this invention there was a lem. The present invention overcomes these objections by providing an automatic selective phonograph of the type mentioned, with a plurality of isolated controllers adapted to select from the selective phonograph and deliver to the isolated point one or more of the sound renditions desired.

The combination of an automatic selective pho nograph adapted and used with one or more selective remote control devices is not only selective as to musical renditions, but is multi selective as to the audience or distributing points. A patron at, each distributing point can not only select, but after he has selected, can control his selection as to the volume which best suits his tastes.

A principal object of the invention provides for the use of a plurality of coin controlled remote control devices which may be placed at one or more sound isolated positions and wired to any selective type sound reproducer such as'an automatic record changer equipped withather- 0 mionic amplifier. Each remote controller is carenditions as desired by the operator upon the deposit of the proper coin or coins.

Another object of the invention provides for the construction of a complete selective remote ticularly to a new and novel coin-operated conable in the automatic instrument to which it iswidespread demand for the solution of this prob-' pab-le of reproducing one or more selected sound UNITED STATES PATENT OFFICE nemo'ra comm. omen Lloyd 1.

control device including loud speaker in one small compact casing adapted to be operated by the deposit of a coin and enabling an operator to select one or more sound reproductions upon the deposit o!v a proper coin or coins and have com- 5 plate manual control over the volume of sound emitted.

A further object of the invention provides for a loud speaker and internal sound chamber designed to produce high quality reproduction withdeposited.

Referring to Fig. 1, the front cover or casing I, contains a cylinder lock 2, selector knob 3, volume control knob 4, an indirectly illuminated program plate assembly 5, and loud speaker grille 6.

The work ng parts are shown in Fig. 4 mounted on a back plate or rear casing 'l. The combination coin receiver and slug detector 8 is mounted in the upper end thereof. Volume control 9, selector swi-tch ill and cut-out switch Sit-39 are mounted to a suitable suspension bracket lz;

The shafts for the volume control land the selector switch iii are slotted so as to axially and rotationally engage with the shafts of the con-- trol knobs 3 and 4 shown in Fig. 1. Fig. '7 shows the method employed for engaging the knob shaft The loud speaker I6, Figs. 4 and 5,18 attached to the back plate in a position to correspond with the hole in the baflle of the cover I. A terminal strip l1, Fig. 4, is provided as a junction to which are attached the control cable wires from the selective sound reproducer.

When a coin is deposited through the metering plate l8, it falls by the action of gravity through coin receiver 8 and impinges upon petal 19, which momentarily closes switch 20, Fig. 4. After closing the momentary switch 20 the coin falls into and is retained by bag l3.

Utilizing well known means, spurious coins are deflected and by-passed over petal l9 directly into the money bag l3, thus avoiding the closing of the momentary switch 20. 3.

Referring to Fig. 5, the cover i is removed from the back plate I by.unscrewing cylinder lock 2 which permits the cover to be drawn forward and downwardly releasing it from the dowel pins 2| which are anchored in the back plate, Figs. 1 and 5.

The program assembly 5, Fig. 5, is mounted behind glass window 22 and is slottedfor the passage and diifusion of light. Thus the printed strips 23, which are attached to the inclined portions of the program plate, are illuminated by lamps l5.

Spring clips 24 are provided to retain the pro-.

gram plate assembly in its proper position and also provide means for quickly detaching the assembly to facilitate the changing of the printed program slips.

The loudspeaker l3, Fig. 5, is shown positioned behind the circular baflle plate and air seal 25 directly to the rear of the wire cloth grille 6.

The volume control 9, shown in Fig. 4, is a conventional variable resistance L pad shown in the circuit diagram and its action will be hereinafter described.

The selector switch Ill, shown in section in Fig. 6, is an insulated multi-contact unit provided with a detent 26. The contact arm 21,

which carried an ordinary brush member, is held into contact with any one of radial contacts 28 by the detent action of the ball 26 resting in radial depressions in a plate 29, which depressions correspond in number to the contacts 28.

The slotted shaft 30 is shown in engagement with a pin which is integral with the collar 32 and the knob shaft 33.

Referring to Figs. 5 and "I, a locking arm 34 is provided to prevent normal rotation of the control knob. The arm 34 is integral with the knob shaft 33, shown in Fig. 6, and hasstuds 3| attached to the ends thereof for normal engagement with a fixed metering plate 36, shown in Figs. 5 and 7, which of 'the cover I.

The spring 31 between the casing and the control knob, Figs. 5 and 6, normally urges the locking arm pins 3| into engagement with the holes the L pad 9.

plate is amxed to the inside in locking plate 36, thus normally preventing the depressing the insulator which is attached to the H inner switch spring 39.

. In actual operation the operator chooses a selection from the program plate 5, Fig. 1, and then depressesthe control knob 3 inwardly and turns theknob pointer H to a number, onthe selector plate as shown, corresponding to the selection desired. While the knob is depressed, switch 3833 is opened and the locking arm 34 of the selector switch is-free to rotate. When the knob is released the locking arm 34 reengages plate 36 and prevents fur her rotation and simultaneously the switch 38 is closed.

A coin may then be deposited in the coin receiver plate l8 and the weight of the coin depresses petal I9 closing the contacts 20 momentarily which completes a circuit to the selective sound reproducer through breaker switch 3833,

switch contact arm 21 and a corresponding contact 28.

Since it is necessary to move the selector knob to disengage the locking arm 34 from the plate 36, which causes the switch 3339 to open, an operator is prevented from obtaining more than one selection upon the deposit of a single nickel, which would be thecase if the above means were not employed, as it is obvious an operator could deposit a coin and thus momentarily close the switch 20 and simultaneously rotate the selector switch and energize more than one external circuit.

When the selective sound reproducer starts its operation the sound output line of thereproduce'r furnishes the loud speaker It with the rendition selected. The volume of sound output from the loud speaker may be adjusted to suit the operator by means of the control knob 4 which rotates lines connecting the above devices to the sound reproducer represent multiple cables and are equivalent to the conductors 46 of Fig. 3. The wiring diagram, Fig. 3, shows the circuit employed in connecting one remote controller device to a selective sound reproducer. When more than one remote controller device is used atone isolated station the conductors are connected in parallel.

Alternating current power is supplied to the remote controller 'by transformer 40, one terminal of the secondary of which is connected to the common line 4| of the selective reproducer and the other terminal connected to one side of the momentary switch 20. The opposite side of the momentary switch is connected to the rotary arm 21 of the selector switch through manual breaker switch 38; thus when the selector knob is pushed inwardly the arm 21 can be moved to a-desired contact 28, the breaker switch preventing the completion of the circuit, and by releasing the selector knob, a circuit may be establishcd through the closed breaker switch and the momentary switch 20 by the deposit of a coin.

and amplifier the sound output of the selective reproduceris connected toterminals'fl and II of each remote control device and run to an impeda'ce matching transformer ll, the secondary of which is connected to the voice coil of the loud speaker through the volume control L pad 9.

Referring to the schematic wiring diagram, Fig. 3, an operator, by pushing the control knob inwardly, as previously described, may rotate the selector switch arm 21 until it rests upon the contact selected, in this case indicated by nural 28. It will be observed that while the operator is rotating the switcharmj'l he has necessarily moved the control knob inwardly, which opens the switch "-49. Upon releasing the control knob the switch 38- is closed by the action of a. spring previously described.

Then, upon the deposit of an appropriate coin in the coin receiver, the switch 20 is momentarily closed, which completes a circuit as follows: From one side of the secondary of the power supply transformer I, through the momentary switch 20, through the breaker switch 1H9, through the switch arm 21 and selected contact 28, from contact 28 through a conductor to a corresponding electro-magnet 4! in the' selective sound reproducer, through conductor 46.

Since one side of all the magnets ll in the 1 sound reproducer are common, the circuit is completed through a conductor to terminal ll and return to the remaining side of the secondary, of the power transformer.

Conductors l2 and 48 are connected to the sound output of theselective sound reproducer and are carried by a pair of conductors to audio transformer. 44 L pad volume control to loud' speaker It. .Thus, upon the tripping of a selected magnet" 45 reproduction corresponding to this magnet will be delivered to the loudspeaker It the device.
